Double Impatiens plant named ‘Danmubicred’

ABSTRACT

A new and distinct Double  Impatiens  plant named ‘Danmubicred’ characterized by having medium, upright and rounded growth habit; double, red and white bicolor flowers; yellow-green colored leaves and good branching.

Botanical designation: Impatiens walleriana.

Variety denomination: ‘Danmubicred’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Double Impatiens plant, botanically known as Impatiens walleriana, herein after referred to by the cultivar name ‘Danmubicred’.

The new Double Impatiens cultivar is a product of a planned breeding program conducted by the Inventor, Gabriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program is to develop a new Double Impatiens variety with medium, upright and rounded, growth habit, red and white bicolor flowers, yellow-green leaves, and good branching habit.

The new Impatiens cultivar ‘Danmubicred’ originated by selfing an Impatiens walleriana cultivar designated ‘348HF’ (unpatented) in a controlled breeding program by the Inventor in 2002 in Moshav Mishmar Hashiva, Israel. ‘Danmubicred’ was discovered and selected by the Inventor in April of 2002 as a flowering plant within the progeny from the selfing of ‘348HF’ in a controlled environment in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar by stem tip cutting was first performed in July of 2002 in Moshav Mishmar Hashiva, Israel, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true-to-type.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of the new Double Impatiens cultivar ‘Danmubicred’ which in combination distinguish this Double Impatiens as a new and distinct cultivar:

-   -   1. Medium, upright and rounded growth habit;     -   2. Double, red and white bicolor flowers;     -   3. Yellow-Green colored leaves; and     -   4. Good branching.

Plants of the new Double Impatiens ‘Danmubicred’ differ from plants of the parental cultivar, ‘348HF’ (unpatented) in the following characteristics described in Table 1:

Of the many commercial cultivars known to the present Inventor, the most similar in comparison to the new Double Impatiens cultivar ‘Danmubicred’ is a Double Impatiens called ‘Fiesta Sparkler Rose’. In side-by-side comparisons conducted in Moshav Mishmar Hashiva, Israel, plants of the ‘Fiesta Sparkler Rose’ differed from plants of ‘Danmubicred’ primarily in flower color and leaf size as provided in Table 2:

The second photograph shows a close-up view of typical flowers and leaves of ‘Danmubicred’ at 3 months.

DETAILED BOTANICAL DESCRIPTION

The Double Impatiens cultivar ‘Danmubicred’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and daylength, without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe plants of the new Double Impatiens cultivar ‘Danmubicred’ as grown in a greenhouse in Moshav Mishmar Hashiva, Israel, under conditions which closely resemble those generally used in commercial practice. Plants of ‘Danmubicred’ are grown in a greenhouse with day temperatures ranging from 25° C. to 30° C. and night temperatures ranging from 18° C. to 25° C. Plants of ‘Danmubicred’ are fertilized up to a level of 100 ppm N, 35 ppm P and 120 ppm K. The age of the plants described is 8 weeks. The photographs and descriptions were taken during the winter when outdoor day temperatures ranged from 15° C. to 25° C. and outdoor night temperatures ranged from 10° C. to 15° C.

Color references are made with The Royal Horticultural Society Colour Chart (R.H.S.), 2001 edition, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 12 noon in Moshav Mishmar Hashiva, Israel.
